The present invention makes it possible to provide a connector comprising a contact that forms an electric connection with a counterpart contact, having a first contact piece and a second contact piece branched by a bifurcated branching part, as well as a first contact point element provided to the first contact piece and a second contact point element provided to the second contact piece in contact with the surface of the counterpart contact when the counterpart contact is inserted between the first contact piece and the second contact piece. At least one of the contact pieces has a first elastic part that has elasticity and is capable of being displaced in a direction orthogonal to the plate thickness. Providing a part curved in the plate thickness direction between the branching part of the contact pieces and the contact point elements allows the connector to adapt to the space allowed to the connector while maintaining a sufficient elastic force. The contact may have first and second contact pieces that differ in length and shape, but maintaining the contact points at the same position makes it possible to prevent a rotational moment received by the counterpart contact at the time of fitting.
